Device and method for the determination of the electrochemical corrosion potential

摘要

The invention provides at least two electrochemical sensors positioned in a nuclear reactor, wherein at least one of the at least two electrochemical sensors has a zirconium electrode, and the at least two electrochemical sensors produce voltages proportional to an electrochemical corrosion potential for a surface that each of the at least two electrochemical sensors are installed upon. The invention also provides an arrangement configured to accept the voltages produced by the at least two electrochemical sensors, wherein the arrangement is configured to determine an electrochemical corrosion potential of a zirconium fuel rod in the nuclear reactor based upon the voltages of the at least two electrochemical sensors.
